Streamline 1.8.0.1 (Default branch)
Streamline is a pipelined I/O subsystem for both kernel and application processing on Linux, with 40+ filters for pattern matching, stream reassembly, compression, etc. It exports the pipes, sockets, and pcap interfaces and uses shared memory to reduce I/O copy and context switch cost. Logical uses are rapid application development of intrusion detection systems and similar complex network processing tasks. License: GNU Lesser General Public License (LGPL) Changes:
This version updates the stream language to be a superset of Unix shell pipelines and improves support for hybrid pipelines consisting of streamline filters (e.g., in the network stack) and full Unix processes. Because of the extensive interface changes, this version is less mature than 1.7.4.5 and has little documentation (other than the mailing list). Image

Help me streamline this counting part of my script.

Ok, so this is a small part of a script I wrote to build disk groups using VXVM. The only problem is that I am limited to a count of 8 maximum. If I want more, I will have to add more lines of "if" statements. How can I accomplish the same thing, in a few lines, but not be limited in the max... (13 Replies)

OPTIONS

       -b big|little
		 Byte order of output.

       -d debug_level
		 Enable debugging.

       -h	 Display help.

       -n count  Generate count flows.	Default 1000.

       -V version
		 Generate version type exports.  Supported versions are:
